Today, I'm co-hosting an online event on TechSoup about Flickr with Heather Camp, Flickr Community Manager. I love online discussions with a mix of experience. I just learned something really important from colleague Michaela Hackner about uploading.
I think there is a benefit of uploading only 4-6 photos at a time because your followers only see the last 4 images you've posted anyway. Sharing a few photos at a time helps you be more thoughtful about captions, tags, and categorizing, and gives people a chance to catch up on your stream. When I was at the height of my Flickr obsession (and living overseas when I had a lot more time), I limited myself to posting no more than 4 images at a time for this reason.
This event will run today. Ask questions, share your learning, and learn from others. Click here participate.
